There is a separate module for each database back-end. At present support for
-both MySQL and PostgreSQL is implemented. This installation guide assumed that
-you are using MySQL.

+
+#### Setting up the MySQL database
First of all you have to install the `icinga2-ido-mysql` package using your
distribution's package manager. Once you have done that you can proceed with
# mysql -u root -p
- mysql> CREATE DATABASE icinga;
- Query OK, 1 row affected (0.01 sec)
-
- mysql> GRANT USAGE ON icinga.* TO 'icinga'@'localhost'
- IDENTIFIED BY 'icinga'
- WITH MAX_QUERIES_PER_HOUR 0
- MAX_CONNECTIONS_PER_HOUR 0
- MAX_UPDATES_PER_HOUR 0;
+ mysql> CREATE DATABASE icinga;
- mysql> GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE
- ON icinga.* TO 'icinga'@'localhost';
-
- mysql> FLUSH PRIVILEGES;
+ mysql> GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE ON icinga.* TO 'icinga'@'localhost' IDENTIFIED BY 'icinga';
mysql> quit
+
After creating the database you can import the Icinga 2 IDO schema using the
following command:
> On SuSE-based distributions the schema files are installed in
> `/usr/share/doc/packages/icinga2-ido-mysql/schema`.
-### Upgrading the database
+#### Upgrading the MySQL database
If the database has been installed and requires an upgrade, verify the current
schema version first:
+---------+
| version |
+---------+
- | 1.10.0 |
+ | 1.11.0 |
+---------+
Check the `schema/upgrade` directory for an incremental schema upgrade file, e.g.
-if your database schema version is `1.10.0` look for `mysql-upgrade-1.11.0.sql`
-and newer.
+if your database schema version is `1.10.0` look for `mysql-upgrade-1.12.0.sql`
+and newer. If there isn't an upgrade file available there's nothing to do.
Apply all database schema upgrade files incrementially.
- # mysql -u root -p icinga < /usr/share/doc/icinga2-ido-mysql-*/schema/upgrade/mysql-upgrade-1.11.0.sql
+ # mysql -u root -p icinga < /usr/share/doc/icinga2-ido-mysql-*/schema/upgrade/mysql-upgrade-1.12.0.sql
> **Note**
>
> The Icinga 2 IDO module will check for the required database schema version
> on startup and generate an error message if not satisfied.
-### Installing the IDO module
+#### Installing the IDO MySQL module
The package provides a new configuration file that is installed in
`/etc/icinga2/features-available/ido-mysql.conf`. You will need to update the
After enabling the ido-mysql feature you have to restart Icinga 2:
# /etc/init.d/icinga2 restart
+
+
+### Configuring IDO PostgreSQL
+
+#### Setting up the PostgreSQL database
+
+First of all you have to install the `icinga2-ido-pgsql` package using your
+distribution's package manager. Once you have done that you can proceed with
+setting up a PostgreSQL database for Icinga 2:
+
+> **Note**
+>
+> The Debian packages can optionally create and maintain the database for you
+> using Debian's `dbconfig` framework. This is the recommended way of setting up
+> the database.
+
+ # cd /tmp
+ # sudo -u postgres psql -c "CREATE ROLE icinga WITH LOGIN PASSWORD 'icinga'";
+ # sudo -u postgres createdb -O icinga -E UTF8 icinga
+ # sudo -u postgres createlang plpgsql icinga
+
+Locate your pg_hba.conf (Debian: `/etc/postgresql/*/main/pg_hba.conf`,
+RHEL/SUSE: `/var/lib/pgsql/data/pg_hba.conf`), add the icinga user with md5
+authentification method and restart the postgresql server.
+
+ # vim /var/lib/pgsql/data/pg_hba.conf
+
+ # icinga
+ local icinga icinga md5
+ host icinga icinga 127.0.0.1/32 md5
+ host icinga icinga ::1/128 md5
+
+ # "local" is for Unix domain socket connections only
+ local all all ident
+ # IPv4 local connections:
+ host all all 127.0.0.1/32 ident
+ # IPv6 local connections:
+ host all all ::1/128 ident
+
+ # /etc/init.d/postgresql restart
+
+
+After creating the database and permissions you can import the Icinga 2 IDO schema
+using the following command:
+
+ # export PGPASSWORD=icinga
+ # psql -U icinga -d icinga < /usr/share/doc/icinga2-ido-pgsql-*/schema/pgsql.sql
+
+> **Note**
+>
+> The Icinga 2 RPM packages install the schema files into
+> `/usr/share/doc/icinga2-ido-pgsql-*/schema` (`*` means package version).
+> The Icinga 2 dist tarball ships the schema files in `components/db_ido_pgsql/schema/`.
+>
+> On SuSE-based distributions the schema files are installed in
+> `/usr/share/doc/packages/icinga2-ido-pgsql/schema`.
+
+
+#### Upgrading the PostgreSQL database
+
+If the database has been installed and requires an upgrade, verify the current
+schema version first:
+
+ # export PGPASSWORD=icinga
+ # psql -U icinga -d icinga -c "SELECT version FROM icinga_dbversion;"
+ version
+ \---------
+ 1.11.0
+
+Check the `schema/upgrade` directory for an incremental schema upgrade file, e.g.
+if your database schema version is `1.11.0` look for `pgsql-upgrade-1.12.0.sql`
+and newer. If there isn't an upgrade file available there's nothing to do.
+Apply all database schema upgrade files incrementially.
+
+ # export PGPASSWORD=icinga
+ # psql -U icinga -d icinga < /usr/share/doc/icinga2-ido-pgsql-*/schema/upgrade/pgsql-upgrade-1.12.0.sql
+
+> **Note**
+>
+> The Icinga 2 IDO module will check for the required database schema version
+> on startup and generate an error message if not satisfied.
+
+
+#### Installing the IDO PostgreSQL module
+
+The package provides a new configuration file that is installed in
+`/etc/icinga2/features-available/ido-pgsql.conf`. You will need to update the
+database credentials in this file.
+
+You can enable the `ido-pgsql` feature configuration file using `icinga2-enable-feature`:
+
+ # icinga2-enable-feature ido-pgsql
+ Module 'ido-pgsql' was enabled.
+ Make sure to restart Icinga 2 for these changes to take effect.
+
+After enabling the ido-pgsql feature you have to restart Icinga 2:
+
+ # /etc/init.d/icinga2 restart
